LUBRICANT-CUP.

To all whom it may concern:

Be it known that I, Crms'rnn A. BACON, a citizen of the United States, and a resident of Auburn, in the county of Cayuga and State of New York, have invented a certain new and useful Lubricant-Cup, of which the following is a specification.

This invention relates to lubricant cups, and has for its object a particularly simple and efiicient means for securing the cover to the base of the cup, and the invention consists in the novel combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings, in which like characters designate corresponding parts in all the views.

Figure 1 is a sectional view through this lubricant cup, the cover being shown as closed.

Fig. 2 is an elevation, partly in section, showing the cover as opened.

Fig. 3 is a sectional view on line A-A, Fig. l.

This lubricant cup comprises, generally, a base, a cover, and a spring connecting the base and cover and arranged to pivotally connect the cover to the base and to close the cover after the startin impulse has been given thereto and to hold the cover in closed position and also to hold the cover in its extreme open position.

1 designates the base, 2 the cover, and 3 the spring. The base 1 is cylindrical or cupshaped in general form and is provided with a stem 4, which, as here shown, extends laterally from the bottom thereof, and is formed with a threaded nipple 5 for connection to the part to be lubricated.

The cover 2 is a flat lid formed with an annular margin 6, which fits over the upper end of the base 1, and with an outwardly ex tending fingenengaging piece 7.

The spring 3 is hinged to one of the parts it connects and is fixed to the other of said parts, and the spring is arranged so that the cover has a sliding fulcrum on the upper edge of the base 1 during the opening and closing movement of the cover, and swings about an axis located within the base and below the upper edge thereof so that when the cover is opened, a portion thereof laps the side of the base 1 sufliciently to hold the cover in open position, that is, so that the Specification of Letters Patent.

line of force of the spring'is applied to the cover when open, below the point where the cover is engaging the upper edge of the base.

As here shown, the spring includes an arm 8 hinged to the base, and a shorter arm 9 reversely arranged with respect to the arm 8, and secured to the inner side of the cover and lying substantially fiatwise thereon. The axis of the arm 8 is located below the upper edge of the base and between the fulcrum point 10 of the cover on the upper edge of the base 1 and the center or vertical axis of the base; and the point of securement of the spring or arm 9 thereof and the cover, is located between the axis of the arm 9 and a point diametrically opposite the fulcrum point 10 when the cover is closed. 7

In this embodiment of my invention, the spring 3 is double and has branches bent upon themselves to increase the length thereof within the space in which the spring is confined, and it is in the general form of a W and the arms 8 form the outside arms of the W, and the arms 9 the intermediate arms of the W.

The arms 8 are formed with laterally turned ends 11 which constitute hinge pins journaled in suitable holes formed in the base 1 at an appreciable distance below the upper edge of the base 1.

The intermediate arms 9 are secured to the inner face of the cover by a pin or rivet 12 located substantially at the center of the cover.

In operation, when the cover is closed, the spring contracts by its own tension toward a plane, but during the opening of the cover, the cover slidably fulcrums at 10 on the upper edge of the base 1 midway between its iinge pins 11, and the edge of the cover diametrically opposite the fulcrum point of the cover moves in an are about the center of the hinge pins 11, and as the cover slides on its fulcrum point, it bears on the base only at the point 10, and when open the greater portion of one-half thereof laps the side of the base 1 below the fulcrum 10, as seen in Fig. 2. During the opening movement of the cover, the arms 8 and 9 of the spring are separated out of a plane and the spring tensioned so that it tends to return toward said plane. When the cover is open as in Fig. 2, the force of the spring is applied to the cover between the point 10 and point 13, where the edge of the cover engages the base. Hence, the cover is held in its open position by the spring and a starting impulse must be given it before the spring is free to move the cover to its closed position.

WVhat I claim is 1'; A lubricant cup comprising a base, a cover slidably fulcruming on the base, and a spring including reversely extending arms tensioned to flatten toward a plane, one being hinged to the base and the other secured to the inner side of the cover, the latter arm being shorter than the former, substantially as and for the purpose set forth.

2. A lubricant cup comprising a base, a cover slidably fulcruming on the base, and a spring including reversely extending arms tensioned to flatten toward a plane, one being hinged to the base below the point on the base where the cover slidably fulcrums, and the other secured to the inner side of the cover, the latter arm being shorter than the former, substantially as and for the purpose described.

3. A lubricant cup comprising a base, a cover slidably fulcruming on the upper edge of the base, and a spring located on the inner side of the cover and including side arms and intermediate arms reversely arranged with respect to the side arms, the spring being tensioned to flatten toward a plane, the free ends of the side arms being hinged to the base below the upper edge thereof, and the intermediate arms being fixed to the in ner side of the cover, substantially as and for the purpose specified.

4. A lubricant cup comprising a base, a cover slidably fulcruming on the upper edge of the base, and a spring located on the inner side of the cover and including side arms and intermediate arms reversely arranged with respect to the side arms, the spring being tensioned to flatten toward a plane, the free ends of the side arms being hinged to the base below the upper edge thereof. and the intermediate arms being shorter than the side arms and fixed to the inner side of the cover, substantially as and for the purpose set forth.
